Abstract: The present invention relates to an ion generator. The ion generator according to the present invention comprises: a circuit board through which a high voltage flows; a high-voltage electrode to which a high voltage is applied through contact with the circuit; a ground electrode grounded through contact with the circuit and spaced apart from the high-voltage electrode; and a holder kit in which a first insertion groove, into which the high-voltage electrode is inserted, and a second insertion groove, which is spaced apart from the first insertion groove and into which the ground electrode is inserted, are formed in the vertical direction, and thus a stable uniform electric field can be continuously formed through the integration of the high-voltage electrode and the ground electrode by using the holder kit, so that the lifespan of an electrode can be improved and the occurrence of discharge noise can be suppressed.
